This study explored the relationship between educational technology and the mathematics achievement of South African and German students. Hierarchical Linear Models (HLM) showed that the availability of computers at school and using computers in the mathematics classroom in South Africa positively associated with the mathematics achievement of…

The aim of this study is to contribute to a better understanding of challenges and factors which influence learning efficiency with electronic-portfolios. Based on the "Technology Acceptance Model" (TAM; Davis, Bagozzi, & Warshaw, 1989) we analyzed "external variables" (e.g., computer-anxiety) that influence technology…

In recent years digital technologies, such as tablet personal computers (TPCs), have become an integral part of a school's infrastructure and are seen as a promising way to facilitate students' learning processes. This study empirically tested a theoretical model derived from the technology acceptance model containing key constructs developed in…

The present study examines whether the seductive-details effect is moderated by spatial ability and prior knowledge, which are two of the most relevant learner characteristics in multimedia learning. It is assumed that the seductive-details effect with an increase in extraneous cognitive load and a decrease in perceptual processing and learning…

Our study focuses on the correlation of concept map (CMap) structures and learning success tested with short answer tests, taking into particular account the complexity of the subject matter. Novice sixth grade students created CMaps about two subject matters of varying difficulty. The correlation of the complexity of CMaps with the post-test was…

The present study aims at investigating which factors are relevant to induce teachers' student-centered classroom computer use. Survey data were collected from 361 teachers at comprehensive schools. Based on a systemic view of technology use in schools, different individual teacher characteristics and school contextual factors were examined.…

Ruscio, Seaman, D'Oriano, Stremlo, and Mahalchik (this issue) evaluate 22 bibliometric indicators, including conventional measures, like the number of publications, the "h" index, and many "h" index variants. To assess the quality of the indicators, their well-justified criteria encompass conceptual, empirical, and practical…

Recent research has provided evidence that students' computer use at home is positively associated with their performance at school. However, most of the previous studies have failed to take into account the multiple determination of school performance and, in addition, to explain why using computers at home should benefit students' academic…

The universities and faculties which educate teachers of mathematics for teaching pupils/students of any age group from pre-school age to higher education carefully monitor and compare valuable results of this research, detect the areas in which the mathematical achievements of pupils should be improved at the national level and propose the ways…

The use of microworlds (MWs), or complex dynamic systems, in educational testing and personnel selection is hampered by systematic measurement errors because these new and innovative item formats are not adequately controlled for their difficulty. This empirical study introduces a way to operationalize an MW's difficulty and demonstrates the…

This paper focuses on "digital inequality"--a key mediating issue within the education technology debate. In particular, it examines how the social and cultural resources of young people relate to their usage behaviour within the informal space of the Internet and what options are available to counter this digital inequality in terms of…
